Caller: Yes, we need an ambulance, the cops. Somebody is stuck underneath the house.Dispatcher: OK, and what happened to the house?Caller: The house just fell through. The bedroom floor just collapsed and my brother-in-law is in there. He's underneath the house.

Bush is presumed dead, according to officials. Rescuers will likely launch a recovery mission when officials deem it safe enough to do so.

According to Rogers, officials used sound devices that "could hear a mouse walking across a floor," but those devices did not detect any signs of life.

The sinkhole quickly grew to about 30 feet wide and at least 20 feet deep behind the home, according to officials. Rogers said there was no telling how much more the sinkhole could grow. Several nearby homes were evacuated as a precaution.

Engineers condemned the home and said it was unsafe for rescuers to conduct any type of search.

"The problem we have right now is we just don't know how stable the house is," said Rogers.

The house was last inspected in August and showed no signs of trouble, according to investigators at the scene.

The engineering firm was able to drop cameras and audio equipment into the hole, but so far, no contact was made with the man inside.

Public works crews brought in a pipe cam to explore a sewer line adjacent to the victim's home. They're also using ground penetrating radar to figure out how deep the hole is and what it will take to fix it.

Jeff Bush was a state Department of Transportation worker.
